Weekly Bulletin on Solar and Geomagnetic Activity
               Highlights on 03 - 09.07.2017,
                Forecast on 10 - 17.07.2017,
            Carrington Rotation 2192 (23,05.06.2017)
           Earth above the ecliptic (0,8;  1,5) deg. 
              (S35 - N35 is geoeffectiveness zone)

 SUNSPOT-FORMING ACTIVITY  WAS ON THE MIDDLE LEVEL, 7-8.07 ON THE 
 LOW  AND VERY LOW IN OTHER DAYS.  3 AND 4.07  WERE NEXT SPOTLESS 
 DAYS (44 IN THE 
CURRENT YEAR). THE ESTIMATED, MOST LIKELY WEEKLY AVERAGE VALUE OF 
THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM (old) FOR 
THE PERIOD IS W= 009+10/-9 (Wn= 015+15/-15). ON THE VISIBLE SOLAR 
DISK ONE SUNSPOT GROUP, WHICH AREA HAS BECOME A BIG 9.07 (AR12665 
S05L109, Sp = 740 msh, M_1) APPROXIMATE JUPITER SIZE WAS OBSERVED. 

 NEXT WEEK SUNSPOT-FORMING ACTIVITY  IS EXPECTED AT THE LOW AND VE-
RY LOW LEVELS. THE ESTIMATED,  MOST LIKELY WEEKLY AVERAGE VALUE OF 
THE RELATIVE SUNSPOT NUMBER  IN THE INTERNATIONAL SYSTEM (old) FOR 
THE NEXT WEEK IS W = 20+20/-10.

 FLARE ACTIVITY WAS AT THE MIDDLE LEVEL AT 3 AND 9.07, AT THE LOW
4, 7, 8.07 AND AT VERY LOW IN OTHER DAYS. ONE SOLAR FILAMENT EJEC-
TIONS OCCURRENCES THROUGH THE PERIOD.  ACCORDING TO THE DATA FROM 
SOHO AND STEREO CORONOGRAPHS, >10 CMEs.

NEXT WEEK FLARE ACTIVITY IS EXPECTED THE MIDDLE, LOW AND THE VERY LOW 
LEVELS.

ON THE VISIBLE SOLAR DISK THE FOLLOWING CORONAL HOLES WERE OBSERVED:

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS NOT 
OBSERVED.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT OF VERY 
HIGH LEVEL IS EXPECTED 10 - 14.07.

GEOMAGNETIC CONDITION WAS QUIET AND UNSETTLED ALL DAYS TO 9.07 WHEN 
AFTER ARRIVAL OF THE WEEK INTERPLANETARY SHOCK (08/2300 UT) WAS OB-
SERVED SOME PLANETARY SUBSTORM OF INTENSITY (G1) AND DURATION 6-3 h.
BUT END OF THE DAY BEEN REGISTERED MINOR MAGNETIC STORM(G1, Ams= 30, 
dur.=12 h.) ACCORDING IZMIRAN DATA AND (G0, Ams= 25, dur.=12 h.) AC-
CORDING OF THE CENTER BOULDER DATA. 

 ON THE NEXT WEEK THE QUIET AND UNSETTLED GEOMAGNETIC CONDITION BE EX-
PECTED.
